I inherited mine from my father. I have a 6 and 7 year old and I prayed to all the gods that they wouldn’t have it. So far so good. Starting your daughter this early will probably help. If insurance covers it I would definitely do it. The next generation of stutters will have a harder time due to social media. Someone recording and making memes and so on. So it’s best to try to tackle it now. As she gets older, prepare her for what’s to come. My parents didn’t do either of that.
